Sophisticated attackers often bypass EDR by hiding lateral movement and credential theft inside encrypted protocols like Kerberos and MSRPC, leaving critical breach activity undetected. Nearly 80% of threats rely on malware‑free techniques that mimic legitimate behavior, making encrypted traffic a major blind spot. Additional gaps appear on unmanaged devices such as IoT and OT systems where EDR agents cannot be deployed. These limitations lead to operational burnout as teams struggle to investigate incomplete data. Because adversaries may already be inside the network, detecting post‑EDR breaches requires deeper visibility beyond endpoint‑based defenses.
